以陕西大海则煤矿为例,研究了多层含水系统矿区疏干条件下的含水介质和边界条件特征,建立了研究区三维地下水流数值模拟模型,完成了模型识别和验证,并结合大海则煤矿的工况特征和矿井生产过程,以首采区回采工作面月掘进进度为单位,采用丰水期和平水期两种预测方案,依次对各回采工作面地下水位疏降至2号煤底板的涌水量进行模拟和预测。该方法将复杂空间地质体和地下水渗流相结合,准确描述了疏降工程的降水过程,所得结果既充分保证了矿井的安全生产,又加强了地下水资源保护。
以陝西大海則煤礦為例,研究瞭多層含水繫統礦區疏榦條件下的含水介質和邊界條件特徵,建立瞭研究區三維地下水流數值模擬模型,完成瞭模型識彆和驗證,併結閤大海則煤礦的工況特徵和礦井生產過程,以首採區迴採工作麵月掘進進度為單位,採用豐水期和平水期兩種預測方案,依次對各迴採工作麵地下水位疏降至2號煤底闆的湧水量進行模擬和預測。該方法將複雜空間地質體和地下水滲流相結閤,準確描述瞭疏降工程的降水過程,所得結果既充分保證瞭礦井的安全生產,又加彊瞭地下水資源保護。

Taking Dahaize Mine as the example,the paper establishes a 3D numerical simula-tion model of groundwater movement through analyzing the aqueous medium and boundary con-ditions characteristics in mining area with multilayer aquifer system under the condition of dewa-tering and completes the model identification and verification. According to the working condi-tions and the production progress in Dahaize Mine,based on the monthly driving schedule in working face of first mining area as the unit,it adopts two prediction schemes of wet season and medium season,to simulate and predict the water inflow that underwater level dewatered to the No.2 coal seam floor in turn. Combining the complex geological bodies with the seepage of groundwater,this method exactly describes the dewatering process,and the result obtained from it is not only a guarantee of safe production of the coal mine,but also a protection for the ground-water resources.
